Joe added you as a friend on Facebook. We need to confirm that you know Joe in order for you to be friends on Facebook.
This is the message one receives when someone requests to be added as a friend on Facebook. As I mentioned earlier, the average Facebook account about has 100 friends. Many have much higher friend totals. What is a friend? A Facebook friend is anyone whom you are willing to give permission to view your Facebook page, your “wall.” That is one way to define a friendship. Others, in pragmatic, informal ways define friendship according to life experience. So a friend could be someone who is always there for you. But what does “always there for you” mean? Does it mean someone who never criticizes or corrects you? Does it mean someone who only says good things about you? Does it means someone who will always listen? Or is a friend any casual acquaintance from a social networking site?
